SIMPSON Consulting Eledtrical Engineer GENERAL The organization of the Lighting Department of the City of Tacoma may be considered as consisting of two separate and distinct divisions, the Accounting Division and the Engineering Division. The administration of the former is divided between the Commissioner of Public Works, the Comptroller and the Treasurer. The management of the latter remains entirely with the Commis- sioner of Public Works, who appoints, and acts through, the City Electrician. Subordinate to this latter official are the following sub-departments : SUB-STATION. METER DEPARTMENT. LINE CONSTRUCTION DEPARTMENT. ARC AND NERNST LAMP DEPARTMENT. In addition to the above, there has recently been created a system of maps and records which is subordinate, in part, to the Accounting Division, and in part to the Engineering Division. Electrical current is supplied by the Seattle-Tacoma Power Com- pany, a corporation which operates a hydro-electric plant at Snoqualmie Falls, distributing power from that point to the cities of Tacoma, Seattle and Everett, as well as to a number of towns and villages. Under the terms of a contract entered into under date of November 8, 1907, between the City of Tacoma and the Seattle-Tacoma Power Company, the latter agrees to furnish at the bus-bars of the city’s switchboard an amount of electrical current, not to exceed a maximum of 5,000 horsepower, for a period of five years, the city agreeing to pay therefor at a rate of l*4c per kilowatt hour, as indicated by watt-hour meters placed on the city’s feeder panels. Such meters to be owned by the city. For further information in regard to the provisions of this con- v J tract, reference is made to the original thereof, which is filed in the office of the Commissioner of Public Works. 1 0882 1 i 4 CITY OF TACOMA LIGHTING DEPARTMENT. ACCOUNTING DIVISION All detail records of the department are kept in the office of the Chief Clerk of the Lighting Department, an official appointed by, and acting under, the authority of the Commissioner of Public Works. The principal records of this office are the meter registers. These are books exhibiting a record of current consumed by each customer, and are the nearest approach to a customer’s or individual ledger kept by the department. They are posted from the meter reader’s reports, extensions being made for the net amount of current con- sumed between meter readings at the proper rate per kilowatt hour. The arrangement of these books is such that it is practically impossible to maintain the accounts in the order of the meter reader’s routes, a circumstance which very much increases the diffi- culty and labor of their keeping. This trouble would be entirely obviated by the substitution of either loose leaf binders, or a card cabinet, for the present bound volumes. Bills, or, more properly, receipts, are made from data contained in the meter registers, the total number of receipts for all electricity consumers in one of the city districts being transmitted by the Chief Clerk to the Treasurer; at the same time the meter registers, from which the receipts are made, are temporarily surrendered by the Chief Clerk to the Comptroller, who, from the footings thereof, enters a charge, covering the entire amount, against the Treasurer. The above transaction creates a cash liability upon the part of the Treasurer which is entirely artificial, and, owing to the lack of any record which would permit of credit entries in the individual accounts, leaves that officer without adequate means of protecting himself against loss. The installation of an individual ledger and the placing into effect of a system whereby a charge could only be made against the Treasurer for cash paid into his office, would certainly permit of a more accurate understanding of conditions from an examination of the books, and would also materially reduce the Treasurer’s hazard of financial loss, which is now very considerable. The general records of the department are in the custody of the Comptroller, in whose office they constitute a part of the general records of the city. Any consideration of the methods of accounting applied to Lighting Department records, in this office, as separate from the other city books, would be improper and therefore foreign to this investigation. However, the fact that no account has been taken of depreciation (other than the cost of repairs actually made), due to age and other causes, in the value of the department’s property, is evidence of the necessity of reducing certain property accounts at the expense of apparent earnings. For this reason it is recommended that the property of the depart- ment be inventoried and its value ascertained by a duly qualified board of appraisers. The results of this appraisal to be used as a basis of entry in the correction of the general accounts. A system of maps and records has recently been inaugurated, which, although far from complete at present, is excellent in prin- ciple. While, to a certain extent, the work of this department belongs to the Accounting Division, its greater importance is in con- nection with the Engineering Division, and it will be mentioned further under that heading. CITY OF TACOMA LIGHTING DEPARTMENT, ENGINEERING DIVISION City Electrician. Under the present organization the office of the City Electrician is little more than that of a general foreman. His remuneration and the duties required of him are upon a par with tfyose connected with such a position in the order of most public service corporations engaged in the sale of electric current. There should be created the office of Superintendent (or Manager) of the Lighting Department, which should at all times be filled by a man experienced in the management of properties of similar nature and magnitude. He should also be possessed of a thorough technical understanding of the matter and forces under his supervision. It is, of course, super- fluous to say that such an office should in no sense be of a political nature. Sub-Station. All control apparatus is located in the sub-station building of the Seattle-Tacoma Power Company, at Hood and Nineteenth streets, and consists of sixteen marble panels carrying instruments for the regu- lation of alternating current commercial feeder circuits, two wooden panels temporarily arranged for the same purpose, and thirteen marble panels for the control of the same number of series street lighting circuits. In addition to the above there is one direct current, 600 volt power circuit, and one series street lighting circuit, the instruments for the control of which are temporarily mounted on wooden panels. The present system of distribution consists of eleven single phase and one four-wire two-phase commercial circuits, carrying alternating current at a frequency of 7,200 alternations per minute, and at a nominal pressure of 2,300 volts; one 600 volt direct current commer- cial power circuit, and fourteen alternating current 6.6 ampere series street lighting circuits. Two phase alternating current at 2,300 volts potential is delivered by the Seattle-Tacoma Power Company to bus-bars placed in the rear of a switchboard consisting of ten marble feeder panels. These ten panels constitute the original commercial switchboard and are at present occupied from left to right as follows: No. 1 . Mason Library Circuit. No. 2. Old Town Circuit. No. 3. South Tacoma and Sixth Addition Circuit. No. 4, Lower Pacific Avenue Circuit. No. 5. Old Town Circuit (temporarily cut over from No. 6. Tacoma Avenue Circuit. No. 7. Pacific Avenue Circuit. No. 8. Sixth Avenue Circuit. No. 9. C and Jefferson Streets Circuit. No. 10. Hill Circuit. The six remaining marble panels are new, and three only are as yet in service, which are occupied as follows: Court A Circuit. Sixth Avenue Circuit. Hill Circuit. 6 CITY OF TACOMA LIGHTING DEPARTMENT. The two latter circuits are not as yet removed from their old panels, and can be controlled from either the old or new board. A wooden panel, No. 11, carries the “Commercial Street” circuit, while a two phase circuit designated “Tide Flats Circuit” has its instruments temporarily mounted on a wooden frame. All of the above circuits receive current from the bus-bars above mentioned, to which power is delivered by the Seattle-Tacoma Power Company, through a polyphase graphic recording watt-meter. This instrument produces a record showing the load upon the above men- tioned bus-bars at all hours. During the period of this investigation all power received for the city’s street lighting system was taken from these bus-bars and was therefore recorded as a part of the load indicated by the graphic watt-meter. It is, however, the practice at times to service the street lighting circuits direct from the bus-bars of the Seattle-Tacoma Power Company, and, at such times, the load produced by them is recorded on the chart of a Bristol recording watt-meter. The 600 volt direct current power circuit receives current from the power company’s direct current bus-bars, and the load produced by it is recorded by a Bristol recording watt-meter. The maximum amount of power demanded by the department at any instant is indicated by the sum of the quantities shown at that instant on the charts of the three above mentioned instruments. Each single phase feeder circuit and the 600 volt direct current circuit is provided with an integrating watt-hour meter. The street lighting circuits are equipped with two such meters. The two phase “Tide Flats” circuit has an integrating watt-hour meter connected in one of its phases, the practice being to multiply the amount registered by a constant of two, the result being accepted as the total amount of power consumed on both phases of the circuit. This practice will be mentioned later under its proper heading. Two Bristol recording volt meters are connected to the two phases of the department’s bus-bars. The purpose of these instru- ments being to determine any variation in voltage above or below 2,500 volts, the amount of such variation being speodfied in the city’s contract with the power company, and limited to three per cent. Each alternating current feeder circuit (with the exception of the two phase “Tide Flats” circuit) is equipped with a regulator, which permits of separate voltage regulation of each circuit so supplied. There are also installed thirteen constant current transformers and a series street lighting regulator in connection with the fourteen street lighting circuits. During the investigation the following meters were carefully tested: All intergrating watt-hour meters, the graphic recording watt-meter, the direct current Bristol recording watt-meter. All potential and series transformers connected with above meters. In the making of tests the following instruments were used: Westinghouse portable, single phase watt-meter, style No. 34418. serial No. 104. Thomson A. C. Am. meter, style No. 76999. Westinghouse Am. meter, style No. 35120', serial No. 157. Westinghouse series transformer, style No. 35591, serial No. 972. CITY OF TACOMA LIGHTING DEPARTMENT. 7 Westinghouse series transformer, style No. 35591, serial No. 683. Westinghouse polyphase watt-meter, style No. 34430, serial No. 395. Weston D. C. — A.

These instruments were examined at the testing laboratory of the University of Washington immediately prior to use in this investi- gation. Copies of standardization certificates are included in the supplement to this report and the originals thereof are filed in the office of the Commissioner of Public Works. Watt-hour meters on panels 1, 2, 3, 4 and 11 are connected with their series, or field, coils in circuit between the bus-bars and the feeder regulator, while their shunt, or potential, coils are connected across the circuit beyond, or on the line side of the regulator. This manner of connecting is plainly incorrect, and introduces an error in the amount registered, which is proportional to the voltage varia- tion, caused by the regulator, above or below the voltage of the bus- bars. It is impossible to arrive at the exact amount of the error in the present case, but it is reasonable to assume an average voltage on these feeders not less than 5 per cent, above that of the bus-bars. It may be assumed that from this cause alone the bills rendered by the Seattle-Tacoma Power Company, for power consumed on the circuits affected, are not less than 5 per cent, in excess of a proper charge for same. The following table is compiled from meter tests made during this investigation. The “kilowatt hours registered” column and the two error entries marked * are derived from information received from tire Chief Clerk’s office. The meter error at 3/5 load has been used whenever a reading at that load was available; when no reading at 3/5 load could be made, the percentage of error at that point has been derived by a process of interpolation. All meters exhibiting an error of less than 2 per cent, at 3/5 load are assumed to be commercially correct. Feb. 1908. K. W. H. K. W. H. Panel. % % K. W. H. Error. Error. No. Load. Fast. Slow. Reg.

Attention is called to copies of meter tests, which are included in the supplement to this report, the originals thereof having been filed in the office of the Commissioner of Public Works. Each test was made in the presence of an authorized representa- tive of the power company, who has attached his signature to the original test above mentioned. The defective and improperly connected meters should be cor- rected at once, and all meters should be inspected at least once each six months. As above mentioned, the two phase “Tide Flats” circuit is provided with a watt-hour meter in one of its phases only. This was done apparently upon the theory that the load carried by this circuit was evenly balanced between its two phases, a condition rarely met with in practice. It is recommended that the other phase of the circuit be provided with a watt-hour meter at once. The graphic recording watt-meter, which is installed on the power company’s main feeders for the purpose of ascertaining the load upon the city’s bus-bars, was tested between 6:35 p. m. and 7 p. m., February 25th. The result of three observations made at this time, with a load varying from 4,000 to 4,500 horsepower, shows this instru- ment to be approximately 2 per cent, high under the heavier loads. A record of this test is included in the supplement hereof. The Bristol recording watt-meter, which indicates the load upon the 600 volt direct current power circuit, was tested at 11 a. m., February 25th. The load upon this circuit is of an extremely variable nature. The result of the tests made, however (as shown in the sup- plement), is evidence of the commercial correctness of this instrument. All feeder regulators and constant current street lighting trans- formers are placed in the basement directly beneath that part of the building occupied by the department’s switchboard. The extremely crowded arrangement of this apparatus creates a condition of great hazard, not only as the possible cause of a serious interruption to the service, but as a menace to the lives of all those attendant upon it. All of the older station wiring is of poor design and workmanship and is very much crowded. Owing to the lack of available space in the power company’s building (the design of which is little adapted to the department’s requirements), it is impossible to, in any considerable degree, remedy these conditions, and steps should be immediately taken toward the removal of the department’s apparatus to more commodious quarters. This subject will be mentioned later under another heading. CITY OF TACOMA LIGHTING DEPARTMENT. 11 METER DEPARTMENT This department, which should occupy a position of the greatest importance, is practically destitute of every facility requisite to the proper performance of its functions. Such instruments as are pro- vided are old and out of adjustment. The 1 number of men employed is sufficient only to the execution of the most imperative demands, while less pressing but equally important work is left without atten- tion. No criticism of the men employed is here intended, as the conditions under which they labor are such that better results could be attained by no others. The meter department has its quarters in a small room partitioned off from the Chief Clerk’s office in the City Hall. This room it shares with the Nernst lamp trimmers, who occupy fully one-half of the available space. Here one, or at times, two men are employed in the repairs and adjustment of watt-hour meters. Meter readers are employed in a sufficient number, but very properly they are fully occupied in reading meters and are available for no other work of importance. New meters are installed, as required, on customer’s premises, after which little attention is paid to them unless the customer com- plains, or the possibility of error is brought forcibly to the attention of the department in some other way. A thorough meter test is impossible, owing to the lack of proper facilities, and upon account of inaccuracies in the instruments now used as standards by the department. During the progress of the present investigation thirty-seven (37) watt-hour meters were exam- ined on customers’ premises. One test only of each meter was made, and that under as nearly a full load as could be secured. All meters within 2 per cent, of accuracy were considered as being commercially correct. The results are as follows: 13 correct. 12 fast. 12 slow. Copies of the test sheets made are filed with the Commissioner of Public Works. Owing to the shortness of the period of time available for this work, no attempt was made to ascertain the condition of these meters except where operating under the loads given. Lyman C. Reed, in his “American Meter Practice,” has very ably discussed the subject of losses in meters and the result of his analysis shows that, under conditions generally met with, it is reasonable to expect “a general loss of 15 per cent, of the current delivered apd that, too, by meters which, on loads of 20 per cent, of their capacity, are commercially correct.” While this statement was made in 1903, since which date there has been some considerable improvement in the design and manufac- ture of integrating watt meters, it is reasonable to assume that under conditions prevailing in the City Lighting Department, fully 15 per cent, of all power delivered to customers fails to be registered upon the dials of the department’s meters. The tests made, so far as they were extended, showed an approxi- mately equal division of correct, fast and slow meters at full load. 12 CITY OF TACOMA LIGHTING DEPARTMENT. The same meters tested at fractional loads, under which they usually operate, would have shown themselves . to be, in majority, decidedly slow. From the foregoing it is evident that in no branch of the depart- ment is it more important that proper facilities be provided than in the meter department. Each meter should be inspected, and thoroughly tested, upon the customer’s premises at least once each twelve months. For this pur- pose not less than four properly equipped inspectors should be appointed. The duties of these men should extend, not only to the meters in their districts, but to the character of the load carried upon them. There is prevalent, amongst certain customers of elec- tricity in the city of Tacoma, a sincere belief that the amounts charged them for the service furnished are excessive; notwithstanding the fact that the rate per kilowatt hour is extremely low as compared with that established in other cities of the world. There is a good and sufficient reason for this belief in the fact that probably nowhere else is there in use a larger number of low grade and inefficient incandescent lamps. Out of 363 lamps which were in daily use, and which were observed and tested for “watts consumed per rated candlepower” in the con- sumers’ houses scattered over every district of the city, only eight (8) lamps were found which were rated by their manufacturers as “A” grade; all of the remainder of these lamps were either “B” grade, or refilled, and their power consumption per rated candle- power varied from 4.8 to 5.5 watts. A power consumption of 3.5 watts per candlepower is considered fair. The majority of the observed lamps were intended for operation upon 110 volt circuits, while actually the voltage of the circuits upon which they were used varied from 107 to 125 volts. In very few instances was a voltage of 110 observed in the residence section of the city during the early hours of the evening. The result of this injudicious placing of lamps upon circuits to the voltage of which they are not adapted, and also the result of poor voltage regulation, has been to blacken and seriously shorten the useful life of practically all incandescent lamps used in the residence districts of the city. The useful life of a 3.5 watt lamp is approximately 600 hours of burning at normal voltage. At the end of this period the lamp will have deteriorated to very nearly 80 per cent, of its initial candle- power, and its consumption of power per candlepower will have increased from 3.5 to 4.3 watts, or 22.8 per cent. The following table gives the effect of voltage variations upon this “useful life” period of a 3.5 watt lamp, and also shows its power consumption in watts per candlepower at the beginning. This quan- tity is increased by about 23 per cent, at the end of the useful life period, when the candlepower of the lamp has been reduced to 80 per cent, of its initial output. At this point it is most economical to destroy the lamp and replace it with a new one, as a further use of the old lamp results in a rapid decrease in candlepower and an increase in electricity consumed per candlepower, reaching in some cases a value as high as 17 watts per candlehour.

This subject will be discussed further under its own head- ing. The statement has been made previously in this report, in reference to the lamps which are actually in use upon the City’s circuits, that “their power consumption per rated condle-power varied from 4.8 to 5.5 watts.” It must be borne in mind that these quantities are not to be considered as the power consumed per actual candle-power, which, in some instances, must have nearly approached 15 watts, owing to the worn out condition of the lamps. These inferior lamps, requiring an excessive current, worn and blackened by high voltage and age, constitute a reason for complaint upon the part of the customers, which is sufficient to account for any general dissatisfaction which may have been felt during the past win- ter. Conditions were peculiarly aggravated by heavy additions to the load upon all circuits during the summer and autumn of 1907, without a corresponding increase in capacity of line and transformers. To overcome line losses occasioned by these conditions, the de- partment increased the voltage upon certain circuits, both at the sub- station and by the installation of “booster” transformers upon the lines. No attempt could be made to replace lamps already in use by those of higher voltage, as the department has no control over larrups, and the raising of line voltage resulted in the blackening of all lamps upon the circuits affected. In a few instances complaints may have been due to a misunder- standing occasioned by a change in dates of meter readings which made necessary the rendering of bills in certain districts covering periods in excess of thirty days. Such misunderstandings are, how- ever, easily rectified. The principal and only real cause, due to poor lamps and over- loaded circuits and transformers, is just and should be remedied. This subject has been discussed under the present heading, as the remedy, so far as the lamps themselves are concerned, would be pro- vided by a recognized meter department. It is recommended that legislation be enacted authorizing the furnishing, by the department, of all 8, 16 and 32 c. p. incandescent lamps of plain design, used upon its circuits, and raising the rates charged for current by the addition of one cent per kilowatt hour to the present rates. 14 CITY OF TACOMA LIGHTING DEPARTMENT. Based upon the renewal of each 16 c. p. incandescent lamp at the expiration of 600 hours of burning, the cost to the City for lamps alone would be very nearly 6 mils per kilowatt hour. An additional 4 mils per kilowatt hour should almost exactly cover all other expenses incident to the free renewal of lamps. Business houses using arc lamps or Nernst lamps instead of in- candescent lamps, may be excepted from the increased rate. It is further recommended that the business connected with the free renewal of lamps be made a part of the duties of the meter de- partment, in whose hands there should be at all times accurate in- formation concerning voltage, etc., at the point where the lamps were to be used. Lamps should be renewed at the rate of a 16 c. p. lamp (or equiv- alent thereof) for each 35 K. W. H. consumed, this being very nearly the consumption of a 3.5 watt, 16 c. p. lamp, during a period of 600 hours. Samples taken from each barrel of incandescent lamps should be carefully tested both by photometer and for power consumption. Lamps returned by customers in apparently good condition should be tested and, if found to be so, should be re-issued. The working force of the meter department should consist of a foreman, possessing a thorough knowledge of the details of meter con- struction, adjustment and repair. He should also be competent to direct and carry on tests of transformers, arc lamps, etc. Subordinate to the foreman there should be the four inspectors mentioned above, one thoroughly competent electrical mechanic, one lamp tester, and all of the meter readers. The meter department should be provided with the following set of standard testing instruments: 1 Watt meter. 1 Am. meter. 1 Volt meter. Series and potential transformers for above. 1 Photometer. *The above instruments should be of the best make, of laboratory type and of the highest standard of accuracy. They should be re- tained at all times in the testing room and should constitute standards in the calibration of the department’s other instruments. At least once each six months these laboratory instruments should be compared with the standards kept in the nearest testing laboratory. In addition to the above, the department should be supplied with the following portable instruments: 2 Watt meters — indicating. 2 Sets series transformers. 1 Rotating watt pieter. 2 Potential transformers. 2 Am. meters — A. C. 1 Mili volt meter, D. C. 1 Set shunts for same. 2 Volt meters, A. C. and D. C. 1 Split series transformer. 1 Am. meter calibrated for same. CITY OF TACOMA LIGHTING DEPARTMENT. 15 The cost of all necessary instruments should not exceed fourteen hundred dollars. The installation and maintenance of all arc and Nernst lamps can be carried on more efficiently, and with better results, under the direction of the meter department foreman. It is therefore recommended that all arc and Nernst lamp repair- men, trimmers and all those engaged in the installation of these lamps, be placed within the jurisdiction of the foreman. LINE CONSTRUCTION DEPARTMENT Under this heading will be included all that pertains to the City’s pole lines, distributing circuits and transformers. There is entered in the supplement hereof a brief description of each commercial pri- mary circuit and the 600-volt direct current power circuit. The same order has been preserved as was given in the description of sub-station equipment. Immediately following the description of the circuits are lists of all transformers, showing the capacity and connected load of each. These lists are also grouped in the order of circuits given above. The greater part of the matter included under this heading is a compilation of the department’s records. To verify conclusions arrived at relative to energy losses, tests were made as hereinafter described. No attempt was made to ascertain definitely the losses in the secondary circuits, as the magnitude of such an undertaking within the time specified for this investigation precluded the possibility of reaching any satisfactory result. However, from a general considera- tion of the characteristics of all secondary circuits, and from such observations as it was possible to make, an average loss of 3 per cent, of power delivered may be assumed. The information contained in the transformer lists (in the supple- ment) is evidence of a great lack of transformer capacity in practi- cally all circuits, some transformers having connected fully 500 per cent, of the rated load capacity. This circumstance is a very large fac- tor in the causes which produce bad regulation; and it also results in abnormal maintenance charges, due to the number of burned out trans- formers. While it is an easy matter to secure transformers having full load efficiencies ranging from 90 per cent, to 98 per cent., in accordance with their capacities, the “all day” efficiency of transformers in actual service is an entirely different matter. This is due to the fact that transformer losses are made up of two general components, copper loss and iron loss; the former is pro- portional to the square of the current flowing through the transformer, while the latter is independent of the load and constitutes a continuous leak. A transformer having a full load efficiency of 98 per cent, may very readily have an “all day” efficiency of 90 per cent.; in the smaller 16 CITY OF TACOMA LIGHTING DEPARTMENT. capacities the difference is even greater. For the purpose of esti- mating power losses, the transformer losses will be assumed to be 10 per cent, in this report. Observations of the loads carried by the various circuits were made at the sub-station. In some cases the Westinghouse single phase portable watt meter No. 104 was used, while in others the load was computed 'from the disk speeds of the integrating watt meters installed on the feeder panels. Power factors were computed by comparing the volt-amperes in dicated with the watts. Line losses were calculated from the voltage drop at various points in the several circuits, as shown by readings tak- en, at such points, with Weston volt meters 4668 and 4775, and poten- tial transformers 262121 and 205318, under varying loads and power factors. The working organization of the Line Construction Department is under a foreman and consists of a varying number of sub-foremen, linemen and helpers. Sizes of wire are in all cases given in Brown and Sharpe wire gauge. MASON LIBRARY CIRCUIT. This primary circuit consists of No. 00 gauge copper wire from the sub-station to the corner of Prospect and North Twenty-first streets, a distance of approximately 14,500 feet. Beyond this point the cir- cuit extends nearly 3'V 2 miles, the size of conductors gradually re- ducing to No. 4 gauge. The total connected load is approximately 350 K. W. The greatest actual load observed was 150 K. W., at 90 per cent, power factor. Calculated losses in primary conductors aggregate 5.7 per cent, of power delivered to transformers. A booster transformer is installed at North 33d and Proctor streets, by the means of which the voltage of the circuit at that point is raised about 10' per cent. While the percentage of losses in this circuit, beyond Prospect and North Twenty-first streets, is excessive, the amount of load upon that portion of the circuit is relatively small, as compared with the terri- tory covered. It is possible that the present arrangement fulfills the require- ments in as economical a manner as possible. The transformers on the circuit, while in some cases heavily over- loaded, are, in general, of sufficient capacity. The feeder panel at the sub-station should be equipped with a compensated volt meter, to permit of close regulation at Prospect and North Twenty-first streets. OLD TOWN CIRCUIT. The primary circuit from sub-station to Eighth street and Tacoma avenue is of No. 0 gauge copper wire; from this point to the vicinity of Yakima avenue and North Eighth street, it is of No. 00 gauge. A second branch, all of No. 00 wire, reaches the above point from the sub-station via I street; near Yakima avenue and North Eighth street the two branches are tied together. Minor branches and secondary circuits cover territory east of CITY OF TACOMA LIGHTING DEPARTMENT. 17 Prospect and south of Division streets, and extend to vicinity of Me- Carver and North Thirtieth streets. The total connected load is approximately 705 K. W. The greatest actual observed load was 170 K. W. @ 90 per cent, power factor. Losses in conductors from tests made are 2.5 per cent, of power de- livered to transformers. Voltage should be kept constant at Yakima avenue and North Eighth street. A compensated volt meter should be installed at the sub-station for this purpose. The transformers in this cricuit are heavily overloaded and secondary circuits show excessive losses. The branch running to McCarver and North Thirtieth streets is of No. 1 gauge wire. The drop in voltage on this branch at 8:20 p. m., March 15tli, was 160 volts or 7 per cent, of the voltage of the circuit at the point mentioned. The size of the wire in this branch should be increased to double its capacity for one-half the distance from Yakima avenue and North Eighth street to the end of the line. Secondary circuits should be inspected and increased in capacity where necessary. All joints should be soldered, including service connections. SOUTH TACOMA AND SIXTH ADDITION CIRCUIT. This primary line consists of two branches, both of No. 0 gauge wire, extending from the pole near the sub-station to the corner of K and Center streets, a distance of approximately 7,000 feet. At the latter point the circuit divides, one branch extending to South Tacoma, the other covering the district lying to the east thereof. Tlie total connected load on this circuit is approximately 700 K. W. The greatest observed load was 320 K, W. @ 92 per cent, power factor. Booster transformers are installed at Forty-seventh and Union streets, and Thirty-sixth and K streets; at both points the voltage is raised nearly 10 per cent. The total primary loss in this circuit, including booster trans- formers, is approximately 8 per cent, of the power delivered to the transformers. The circuit should be divided at the sub-station, and separate feeder panels should be arranged, one controlling the South Tacoma branch, the other the Sixth Addition circuit. Under the present arrangement it is impossible to secure even fair regulation, owing to the great difference in length and load distribu- tion in the two branches. Both circuits should be increased in carrying capacity to that of No. 00 gauge from the sub-station to the vicinity of K and Center streets. Compensated volt meters should be provided upon each panel, and adjusted for the approximate “load centers” of each circuit. Secondaries should be inspected for unsoldered joints, and should be reinforced where necessary. Transformers on this circuit, as a whole, are ample in capacity. LOWER PACIFIC AVENUE CIRCUIT. This circuit consists of No. 00 gauge wires from the sub-station to the vicinity of Twenty-sixth and D streets; from this point to Fifty- 18 CITY OF TACOMA LIGHTING DEPARTMENT. ninth and East H streets, the line consists of No. 4 gauge con- ductors. The total connected load amounts to approximately 600 K. W., the greater portion of which lies between the sub-station and the inter- section of Twenty-sixth and D streets. The greatest observed load was 260 K. W. at 85 per cent, power factor. In terms of power delivered to transformers, the loss in the primary circuit is approximately 2.5 per cent, between the sub-station and the extremity of the No. 00 copper; beyond this point the losses are excessive, due 1 to lack of copper capacity. However, the comparative load carried upon the No. 4 gauge ex- tension is small at present, having been relieved recently by the removal of a 40 horsepower motor, which had previously been in- stalled at its southern extremity in Bismarck. It is very probable that the necessity will arise within the near future of increasing the size of wire used for a considerable distance beyond the present terminus of the No. 00 gauge copper. The circuit should be watched carefully and no considerable in- crease in load should be accepted upon the portion of the circuit men- tioned, without adequate provision being made in capacity. This circuit forms, with the south section of the C and Jefferson streets circuit, a two-phase power feeder. It is recommended that all transformers (except those feeding two phase motors) lying south and west of the intersection of Delin street and Pacific avenue be cut over to the C and Jefferson street circuit. This will result in establishing a more nearly balanced condition of load between the two phases. A compensated volt meter should be installed upon the feeder panel and adjusted for the new center of load established, after the re- arrangement of transformers suggested above. Especial attention is called to the overloaded condition of trans- formers on this circuit, which should be relieved at the earliest possible moment. TACOMA AVENUE CIRCUIT. The Tacoma avenue circuit is constructed of No. 00 copper for a distance of about 150 feet from the sub-station; from this point the line consists of No. 0 gauge wire (with the exception of four spans of No. 2) to its end. The total load connected amounts to approximately 470 K. W. The greatest actual load observed was 190 K. W. @ 90 per cent, power factor. Approximate loss in primary wires is 2.9 per cent, of power delivered to transformers. The size of wire in this circuit should be No. 00 gauge from the station to the corner of Thirteenth and D streets, a distance of approximately 2,700 feet. All service furnished east of alley between C and D streets from this circuit should be transferred to either the C and Jefferson streets or Commerce street circuits. The Tacoma avenue circuit should be kept free of two phase motors, and switchboard arrangements should be made to permit of its being fed from either phase. Transformers are, in general, overloaded, and secondary circuits in places evidence excessive losses due to lack of sufficient metal and poor joints. All joints should be soldered. CITY OF TACOMA LIGHTING DEPARTMENT. 19 The feeder panel should be furnished with a compensated volt meter set for the corner of Thirteenth and D streets. PACIFIC AVENUE CIRCUIT. This circuit is constructed of No. 00 gauge wire throughout, with the exception of a short extension upon its northern extremity which is of No. 4. Its total connected load is approximately 550 K. W. The greatest load observed was 360 K. W. @ 88 per cent, power factor. The ap- proximate loss in primaries is 2.7 per cent, of power delivered to transformers. (This amount is calculated, no tests having been made.) The transformers on this circuit show overloads, but are now being replaced by those of larger capacity. As a whole the regulation is good, such variations as do occur being caused in a great part by the overloaded condition of the transformers. The Pacific avenue circuit should be relieved of a portion of its load by the Commerce street circuit, which has ample line capacity. A compensated volt meter should be installed at the sub-station and adjusted for the voltage at or near the corner of Pacific avenue and Eleventh street. This circuit should be entirely free from two-phase or large single phase motors. All such motors now connected can be carried upon the Tide Flats power circuit. SIXTH AVENUE CIRCUIT. This circuit is divided at Nineteenth and Hood streets into two general branches. The first consists of No. 00 gauge wire from the sub-station to the corner of Ainsworth and Sixth avenue, at which point a booster trans- former is installed, raising the voltage at that point about 10 per cent. The distance from the sub-station to the booster is nearly 10,600 feet. From this point the feeder runs west on Sixth avenue to Adams street, and is, in the greater part, constructed of No. 4 gauge copper wire. Minor branches, running north and south, are of No. 6 and No. 8 gauge wire. Formerly a back feeder extended east from Sixth avenue and Sprague street. This has been recently removed and the above mentioned booster installed. Incandescent lamps serviced from this feeder east of Sprague street are very much blackened, which is the probable result of cutting transformers over from the back feeder to the main circuit before lowering the voltage thereon. The total connected load on this branch is approximately 300 K. W. and the greatest observed load 162 K. W. @ 90 per cent, power factor. (This latter amount is estimated from readings made cover- ing the entire circuit.) Approximate primary losses are 12 ^ per cent, of power delie vered to transformers. The second branch of the Sixth avenue circuit consists of No. 0 gauge wire from Nineteenth and Hood streets to Eleventh and Tacoma avenue, a distance of about 3,630 feet. From this point to the end of the line at Tacoma avenue and North Sixth street, it is built 20 CITY OF TACOMA LIGHTING DEPARTMENT. of No. 4 gauge wire. A back feeder of No. 6 gauge wire runs on Tacoma avenue from North Sixth to North First street. The total connected load on this branch aggregates 362 K. W. approximately, and the greatest observed load was 186 K. W. @ 90 per cent, power factor. The primary losses in this branch are nearly 8 per cent, of the power delivered to the transformers. This circuit should be divided into two independent circuits at the sub-station, as it is impossible to secure satisfactory regulations with the present arrangement. A compensated volt meter should be set on the first branch for the voltage at Sixth avenue and Sprague street, and another on the second branch for Tacoma avenue and Division street. The copper in both branches of this circuit is entirely inadequate and should be increased by the addition of 105,500 circular mils in the first branch from the sub-station for a distance of 7,500 feet. In the second branch the No. 0 wire should be extended from its present terminus at Eleventh and Tacoma avenue for a distance of 20,000 feet, in place of the No. 4 wire now used. The transformers on this circuit are very heavily overloaded. The secondary circuits should be carefully inspected and increased in capacity where necessary. C AND JEFFERSON STREETS CIRCUIT. This circuit branches north and south from the pole at the corner of Nineteenth and Jefferson streets. The north branch consists of No. 00 gauge wire, which is gradu- ally reduced to No. 6 at the High School building. The south branch consists of No. 00 gauge wire from the sub-station to the vicinity of Thirtieth and D streets, from which point to the end of the line it consists of No. 4 wire. The north branch carries a total connected load of nearly 325 K. W., while 135 K. W. approximately is connected in the south branch. The greatest actual load observed was 172 K. W. at 86 per cent, power factor. Assuming this load to be divided in proportion to the connected load between the two branches, results in 121 K. W. in the north branch and 51 K. W. in the south branch, all at 86 per cent, power factor. Approximate primary losses in the north branch are equivalent to 3 per cent, of the load delivered to the transformers, while in the south branch such losses constitute but 0.83 per cent, of power so delivered. The secondary losses in both branches are in some cases excessive and the transformers are in general overloaded. As the south branch of this circuit is operated in connection with the lower Pacific avenue circuit to form a two phase feeder, and as the north branch constitutes primarily a lighting circuit servicing important business houses, it is recommended that two distinct cir- cuits be formed, one including the north branch and the other the south branch. The south circuit should relieve the lower Pacific avenue of sufficient load to effect a balanced condition between them. CITY OF TACOMA LIGHTING DEPARTMENT. 21 Remarks made relative to capacity of lower Pacific avenue cir- cuit apply to the South C and Jefferson streets circuit equally as well. Compensator should be set for the same location as that upon the lower Pacific avenue circuit. A compensated volt meter should be installed showing voltage at corner of Eleventh and C streets. Transformers and secondary circuits are overloaded, in many in- stances, in both north and south branches. HILL CIRCUIT. This circuit consists of No. 00 and No. 0 gauge copper wire form- ing a mesh surrounding blocks between Nineteenth and Thirteenth streets, Tacoma avenue and D street, from which branches of No. 4, No. 6 and No. 8 wire are run. The total connected load amounts to 915 K. W. The maximum observed load was 310 K. W. at 92 per cent, power factor. The approximate primary losses are 4.1 per cent, of all power de- livered to transformers. Compensator should be set for the voltage at I and Thirteenth streets. While additional copper is required, conditions can be very much improved by the installation of larger transformers, and overhauling the secondary circuits. “COURT A” CIRCUIT. This feeder from the sub-station to the vicinity of Eighth street and Court A is formed of No. 00 wire; from this point to its northern extremity at the foot of Sixth street, it consists of No. 6 wire. The total connected load is 675 K. W. The greatest actual load observed was 196 K. W. @ 90 per cent, power factor. Approximate primary loss is 2.3 per cent, of power delivered to transformers. Two phase motors, or large single phase motors, now connected in this circuit should be transferred to the Tide Flats circuit. COMMERCE STREET CIRCUIT. This circuit is of No. 0000 wire from the sub-station to Thirteenth and Commerce streets; where it branches and continues north on both sides of Commerce street it is of No, 00 and No. 0 gauge for the greater part Of the way to Ninth street, where it ends. The total connected load on this circuit is about 400 K. W. No observation was made of actual load. The primary loss is negligible so far as the purposes of this in- vestigation are concerned. Secondary losses are very considerable and transformers show overloads. This circuit is of ample capacity to relieve other more heavily loaded circuits, which are now carrying secondaries in the territory which properly belongs to it. 22 CITY OF TACOMA LIGHTING DEPARTMENT. TIDE FLATS CIRCUIT. This circuit is a four-wire, two-phase, power feeder and consists of No. 00 gauge wires from the sub-station to Dock and Eleventh streets; from this point it is of No. 4 wire to the end of the line on the east hank of the channel. The total connected load is 155 K. W. No observations were made for actual load, but the probabilities are that it is not less than 100 K. W. at 75 per cent, power factor. Total primary losses are nearly 1% per cent, of power delivered to transformers. This circuit should be extended from Eleventh street north on Pacific avenue, and should carry all motor load possible. DIRECT CURRENT CIRCUIT. For a description of this circuit, see supplement. SERIES STREET LIGHTING CIRCUITS. There are 690 6.6 ampere series arc lamps in service, distributed over the following circuits in the order given: Circuit. A . B . C . D . E . F . G . H . K . M . N .

These circuits are constructed of No. 6 and No. 8 gauge wire. No wire smaller than No. 6 should be used in any part of the dis- tributing system, except, possibly, in making service connections, owing to lack of tensile strength in the smaller sizes. All secondary circuits should be thoroughly grounded and all feeder panels equipped with automatic circuit breakers. The constant current transformers governing the street lighting circuits are, in some cases, heavily overloaded; a condition im- possible to relieve until more space is provided in the sub-station. The total losses in all the street light regulating apparatus are very nearly 3 per cent, of the total load carried. MAPS AND RECORDS. A great deal of excellent work has recently been accomplished by the department in securing information to be used in the compila- CITY OF TACOMA LIGHTING DEPARTMENT. 23 tion of a system of maps and records. This work has, for some reason, been permitted to lapse and the information secured by previous effort is not in such shape that it can be used to the best advantage. All records of transformers, incandescent, arc and Nernst lamps; all records of circuits, including maps, etc., should be in the custody of an experienced electrical engineer, who should have, under the authority of the City Electrician (or Superintendent) complete juris- diction over all extensions and additions to the distributing system and the load thereon. Maps should be completed at the earliest possible moment, show- ing all circuits, and having entered thereon complete information con- cerning same. These maps should be drawn to a scale of not less than one inch to eacn 100 feet of distance. Blue print copies, properly bound and indexed, should be fur- nished all departments of the city government who are in any way interested. All changes should be immediately posted on the original maps and corrections made at reasonable intervals in the copies. POWER CONSUMED MONTH OF FEBRUARY, 1908. K. W. H. K. W. H. K. W. H.

From the above table it may seen that of 803,065 kilowatt hours of electrical power purchased from the Seattle-Tacoma Power Com- pany, during the month of February, approximately 190,276 K. W. H. or 23.69% was lost in distribution. While the maximum total load observed during this investigation was but slightly in excess of 4,500 horse-power, there is no doubt but that demands in excess of 5,000 horse-power have been made upon the department during the past winter. As additional load is constantly accepted, there is no doubt but that a demand largely in excess of 5,000 horse-power will be placed upon the system as soon as the days shorten sufficiently to produce a coinci- dent store and residence lighting and motor load peak. Unless satis- factory arrangements can be made during the present summer for an additional supply of power, it is extremely probable that the depart- ment will be confronted with serious difficulties during the coming winter. It is recommended that efforts be made to secure not less than CITY OF TACOMA LIGHTING DEPARTMENT. 25 1,000 horse-power in excess of the quantity at present reserved by the Seattle-Tacoma Power Company. It is further recommended that there be appointed a Board of Com- missioners, which shall consist of the City Engineer and two other engineers experienced in the erection of hydro-electric and steam elec- tric plants. This Board should be instructed to carefully examine such water- power properties as may lie within a reasonable distance of the City of Tacoma. If any be found, capable of development to the extent of not less than ten thousand (10,000) horse-power, with a load factor of 30%, which can be acquired by the City and developed at a reasonable price, this Board should be instructed to prepare plans and to make estimate of the cost of such acquisition and development. If no such waterpower is available, then should it be required that the Board of Commissioners prepare complete working plans and specifications covering the erection of a steam driven electric generat- ing station of not less than three thousand (3,000) horse-power, and capable of being increased to ten thousand horse-power capacity. Immediate action should be taken upon the recommendation of this Board, and a decision reached relative to same without delay.
